Narrative:
Dec/08. Checking ron oils as aircraft arrived for ron. Aircraft arrived as ron; I svced oils on both engines then entered quantities in logbook blocks. Contacted maintenance control; notified them of oil added as per my on-duty lead; mr X's instruction; advising me it had an engine oil watch. The main engine oil service is a regular afternoon shift task as we try to service oils in the maintenance manual recommended time after main engine shutdown; therefore; the oncoming shift does not have to restart the engine saving; fuel; money; and time. After service in this case; the aircraft was relocated to a hardstand providing gate space for inbounds. Crew called for a maintenance item; an inoperative upper beacon about 20 mins prior to departure. Mechanic mr Y responded to the gate call. He placed the upper beacon on MEL; then returned the logbook to the crew. Flight crew mentioned the oil watch and asked about the oil entry. Mr Y looked at the book; showed the captain where the oil quantities were entered in blocks. When mr Y left; he went to the maintenance ready room with the lead mr west who looked at the MEL; looked at the procedures of 76-99-00 condition C; maintenance procedure step 4. Mechanic went back to place the entry in the logbook although the aircraft had departed. Notified maintenance control. MEL review was not completed -- at least it was not caught. This is normally accomplished by the ron mechanic doing the check. On this night; mr Z complied with an 'overnight check.' the first steps of the check require an MEL review --. Where it should have been caught -- and there is a step for checking the oil quantity. Improved follow-up procedure for MEL's requiring additional repetitive procedures.

Title: MECHANIC REPORTS AN OUTBOUND CAPTAIN NOTICES THE MEL REQUIREMENT FOR ENTERING THE B757-200 ENGINE OIL CONSUMPTION AS A SPECIFIC ITEM; HAD NOT BEEN COMPLIED WITH. REVIEW OF ALL MEL'S WAS MISSED DURING ROUTINE OVERNIGHT (RON) CHECK.
Narrative: DEC/08. CHKING RON OILS AS ACFT ARRIVED FOR RON. ACFT ARRIVED AS RON; I SVCED OILS ON BOTH ENGS THEN ENTERED QUANTITIES IN LOGBOOK BLOCKS. CONTACTED MAINT CONTROL; NOTIFIED THEM OF OIL ADDED AS PER MY ON-DUTY LEAD; MR X'S INSTRUCTION; ADVISING ME IT HAD AN ENG OIL WATCH. THE MAIN ENG OIL SVC IS A REGULAR AFTERNOON SHIFT TASK AS WE TRY TO SVC OILS IN THE MAINT MANUAL RECOMMENDED TIME AFTER MAIN ENG SHUTDOWN; THEREFORE; THE ONCOMING SHIFT DOES NOT HAVE TO RESTART THE ENG SAVING; FUEL; MONEY; AND TIME. AFTER SVC IN THIS CASE; THE ACFT WAS RELOCATED TO A HARDSTAND PROVIDING GATE SPACE FOR INBOUNDS. CREW CALLED FOR A MAINT ITEM; AN INOP UPPER BEACON ABOUT 20 MINS PRIOR TO DEP. MECH MR Y RESPONDED TO THE GATE CALL. HE PLACED THE UPPER BEACON ON MEL; THEN RETURNED THE LOGBOOK TO THE CREW. FLT CREW MENTIONED THE OIL WATCH AND ASKED ABOUT THE OIL ENTRY. MR Y LOOKED AT THE BOOK; SHOWED THE CAPT WHERE THE OIL QUANTITIES WERE ENTERED IN BLOCKS. WHEN MR Y LEFT; HE WENT TO THE MAINT READY ROOM WITH THE LEAD MR W WHO LOOKED AT THE MEL; LOOKED AT THE PROCS OF 76-99-00 CONDITION C; MAINT PROC STEP 4. MECH WENT BACK TO PLACE THE ENTRY IN THE LOGBOOK ALTHOUGH THE ACFT HAD DEPARTED. NOTIFIED MAINT CONTROL. MEL REVIEW WAS NOT COMPLETED -- AT LEAST IT WAS NOT CAUGHT. THIS IS NORMALLY ACCOMPLISHED BY THE RON MECH DOING THE CHK. ON THIS NIGHT; MR Z COMPLIED WITH AN 'OVERNIGHT CHK.' THE FIRST STEPS OF THE CHK REQUIRE AN MEL REVIEW --. WHERE IT SHOULD HAVE BEEN CAUGHT -- AND THERE IS A STEP FOR CHKING THE OIL QUANTITY. IMPROVED FOLLOW-UP PROC FOR MEL'S REQUIRING ADDITIONAL REPETITIVE PROCS.
